The situation is better with the "Disable semaphores for UVDv1" patch from <a class="bz_bug_link bz_status_NEW " title="NEW - [RV620][RV630][RS880] GPU hangs using UVD hardware acceleration" href="show_bug.cgi?id=85320">bug #85320</a>, but still not completely working. Tested with: mplayer -vo vdpau -vc ffh264vdpau movie.mkv It is an older machine (but still serving well): CPU: 32bit Intel P4 MB: MS-6728, Intel 865PE; Notably no MSIs! GPU: RV730 [Radeon HD 4600 AGP Series]; The "abomination" on AGP! distro: gentoo gcc: 4.9.2 xorg: 1.17.1 mesa: 10.5.2 (r600, llvm enabled) xf886-video-ati: 7.5.0 mplayer: 1.2_pre20150214 ffmpeg: 2.6.2 1) Stable kernel 4.0.2 - Movie plays for a few seconds, then the whole desktop freezes. - Keyboard dead, display dead. Ctrl+F1 to switch to console not possible. - Immediate poweroff (ACPI button) makes a clean shutdown. After few seconds not possible, only hard reboot. - Relevant line of dmesg: radeon 0000:01:00.0: failed to get a new IB (-35) 2) Stable kernel 4.0.2 + patch "Disable semaphores ..." - Movie plays for a longer time (10's of second) well. - Then the video stucks in a short loop (~second), while audio, subtitles and rest of the destop still ok. - After longer time (~minutes) audio and the whole desktop freezes. - But I can do Ctrl+F1 to switch to console and even restart X, but the image is corrupted. - Relevant line of dmesg: radeon 0000:01:00.0: failed to sync rings (-35) 3) Kernel 4.1.0-rc2 + ~airlied/drm-fixes (commit 3790e39) - At first, almost the same as in 2), maybe the times are even longer. - But in the end, the whole system freezes, no Ctrl+F1, no clean poweroff. - I have no dmesg saved (at the moment) due to the fatal crash.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
